title: The role of toothpastes in oral malodor management.
abstract: One out of four people suffers from persistent bad breath. In most of the cases, the cause can be found in the mouth, with the presence of tongue coating as the leading factor, followed by gingivitis and periodontitis, and it is referred to as oral malodor. Because oral malodor is the result of the degradation of organic substrates by anaerobic bacteria of the oral cavity, the management is mostly done by masking the odorous compounds or eliminating the cause (bacteria and their substrates) either mechanically or chemically. Toothpaste formulations have been modified to carry antimicrobial and oxidizing agents with an impact on the process of oral malodor formation. We performed extensive literature search regarding the effect of dedicated toothpastes in the management of oral malodor. The main characteristics of the in vitro and in vivo investigations and their most relevant findings are presented for discussion. Even though the amount of publications regarding this topic is far smaller than for others such as caries, plaque control and whitening, antibacterial ingredients such as triclosan and metal ions like stannous and zinc appear to be effective in the control of oral malodor. On the other hand, data supporting the use of hydrogen peroxide, baking soda, essential oils and flavors in the management of oral malodor are rather few and inconclusive.
